Patent CA-2236287-A1 (CA)
Title: Recepteur amdc
Inventor: UMETSU KAZUHIRO
IPC: H04B1/69
Filed: 1998-04-29
Abstract: Dans un récepteur AMDC, un convertisseur analogique-numérique suréchantillonne un signal de bande de base analogique reçu avec un signal d'horloge dont la fréquence est 2n fois plus élevée que celle d'un signal d'horloge de puce et le convertit en un signal de bande de base numérique. Un corrélateur obtient une valeur de corrélation entre ce signal de bande de base numérique et un code d'étalement pilote qui est en synchronisme avec la réception du signal. Une unité de détection de déphasages détermine le déphasage entre le signal de bande de base numérique et l'instant de réception du signal en utilisant la valeur de corrélation obtenue. Une unité de contrôle modifie l'instant de réception de façon à éliminer le déphasage détecté par l'unité de détection de déphasages.

Patent CA-2242006-A1 (CA)
Inventor: SWAROOP ANIL
IPC: G06F17/30
Filed: 1998-06-29
Abstract: A system and method are disclosed for rendering devices on a cluster globally visible, wherein the cluster includes a plurality of nodes on which the devices are attached. The system establishes for each of the devices in the cluster at least one globally unique identifier enabling global access to the device. The system includes a device registrar that creates the identifiers and a global file system. The identifiers include a globally unique logical name by which users of the clusteridentify the device and a globally unique physical name by which the global filesystem identifies the device. The registrar creates a one-to-one mapping betweenthe logical name and the physical name for each of the devices. The system also includes a device information (dev_info) data structure maintained by the deviceregistrar that represents physical associations of the devices within the cluster. Each association corresponds to the physical name of a device file maintained bythe global file system. The device registrar determines for an attached device aglobally unique, device type (dev_t) value; creates dev_info data structure entry and a corresponding physical name; generates a logical name based on the dev_t valueand the physical name; and associates the dev_t value with the device file representing the attached device. Given this framework, a user of the cluster can access any of the devices by issuing the global file system an access request identifying the device to be accessed by its logical name.

Title: Tilting mechanism
Inventor: STEHLIN BERND
IPC: G01M17/08
Filed: 1998-10-08
Abstract: The invention refers to a tilting mechanism for creating track curve-dependent tilt of the superstructure of rail vehicles (1), consisting of a coupling means (15) with which the superstructure (2) is movably connected to a bogie (3) in such a way that the superstructure can be transferred from an upright initial position into a tilted position relative to the bogie and having a drive (31) and an adjusting means including a transfer means (33,34,35), by means of the adjusting means the superstructure can be movably transferred from its initial position into its tilted position relative to the bogie.

Filed: 1998-12-01
Abstract: A submergible system is disclosed which includes a submergible electric motor drivingly coupled to a progressive cavity pump. The motor and pump are driven at the same speeds without the need for a torque-multiplying device therebetween. The motor may be a brushless permanent magnet motor coupled to the pump through a motor protector. A power supply cable is couplet to the pumping system from the earth s surface. A switching circuit is provided adjacent to the motor to receive direct current power via the cable and to apply the power to the motor. The motor may be started from a static condition by applying electrical power via the cable sufficient to overcome the relatively high starting torque of the pump, without the need to reverse or otherwise preload the system. Thereafter, the flow rate of the pumping system may be controlled both in a low speed range of operation of the motor as well as in a higher speed range.

Title: Electromechanical switch for interconnecting two power sources in a selected coupled state
Inventor: SMITH JERRY R
IPC: H02H11/00
Filed: 1997-07-09
Abstract: An electromechanical switching device (10) ensures automatic selected polarity interconnection between terminals of two power sources (14, 12). A double pole double throw (DPDT) switch (34) has three pairs of contacts. A first pair of leads connect to two pairs of contacts in a manner that reverses polarity when switched, while a second pair of leads connect to the other pair of contacts.  A switch controller (36) employs a plurality of coils in electrical communication with the two pairs of leads. The coils are arranged and configured so that, when the two pairs of leads are connected to the respective power sources (14, 12), the coils cause an actuator to move the switch (34) automatically into the correct polarity state regardless of the connections of the leads. The invention is described as a battery jumper cable and to automatically connect like terminals of a pair of batteries (14, 12).  The invention encompasses the method of this device.

Patent CA-2265177-A1 (CA)
Inventor: BARDET LAURENT
IPC: H01R13/635
Filed: 1999-03-09
Abstract: A connector is made with a male body and a female body that can be partially fitted into each other. The female body, within itself, possesses a ring pushed back towards the exterior by a spring. The ring is held inside the female body by a window into which it gets embedded. During the insertion of the male body, a stop of this body pushes the ring back towards the back of the female body. The ring then releases the window which gets embedded in a groove of the male body. The coupling and the fixed joining of the two parts of the connector are then automatic. To uncouple them, it is enough to press on the lever which carries along the window. The spring which pushes back the ring also contributes to the effortless ejection of the male body. It is shown that in no case should force be exerted except in a single direction: a longitudinal direction on the male connector to couple it and a transversal direction on a lever of the window to uncouple the two elements.
